Restaurateur Denny Valentine is evaluating two sites, Raymondville and Rosenberg, for his next restaurant. He wants to prove that Raymondville residents (population 1) dine out more often than Rosenberg residents (population 2). Denny commissions a market survey to test this hypothesis. The market researcher used a random sample of X families from each suburb, and reported the following:

1 = X times per month and 2 = X times per month. Assume that σ1 = 2 and σ2 = 3. With α = .01, the appropriate decision is:_________

Answers

Answer 1

Answer:

Step-by-step explanation:

From the information given:

let [tex]\mu_1[/tex] be the men of the population 1 (Raymondville) and [tex]\mu_2[/tex] be the mean of the population 2 (Rosenberg).

Here the Restaurateur wants to prove that Raymondville residents dine out more often than Rosenberg residents.

i.e [tex]\mu_1 > \mu _2[/tex]

The null hypothesis and alternative hypothesis:

[tex]H_o : \mu_1 \le \mu_2 \\ \\ H_a: \mu_1 > \mu_2[/tex]

[tex]H_o : \mu_1 \le \mu_2\ \ vs \ \ H_a: \mu_1 > \mu_2 \implies \text{upper tailed test}[/tex]

The shows that this test is one-tailed with the rejection area on the right side.

The appropriate decision: is to reject [tex]\mathbf{H_o}[/tex] if the test statistics is greater than the critical value)

Enter the number that

(-1,-3)

Answers

Answer:

50

Step-by-step explanation:

[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }}[/tex]

Distance between the 2 points

[tex] = \sqrt{( - 3 - 2) {}^{2} +( - 1 - 4) {}^{2} } [/tex]

[tex] = \sqrt{( - 5)^{2} + ( - 5)^{2} } [/tex]

[tex] = \sqrt{25 + 25} [/tex]

[tex] = \sqrt{50} [/tex]

Thus, the number that goes beneath the radical symbol is 50.

Find an equation of the tangent line to the curve at the given point. y = x3 − 3x + 2, (3, 20)

Answers

Answer:

[tex]y - 20 = 24(x - 3)[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope form, has the following format:

[tex]y - y_0 = m(x - x_0)[/tex]

In which the point is [tex](x_0,y_0)[/tex] and the slope is m.

(3, 20)

This means that [tex]x_0 = 3, y_0 = 20[/tex]. So

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 20 = m(x - 3)[/tex]

Slope:

The slope is the derivative of the function at the point:

The function is:

[tex]y = x^3 - 3x + 2[/tex]

The derivative is:

[tex]y^{\prime}(x) = 3x^2 - 3[/tex]

At the point, we have that [tex]x = 3[/tex]. So

[tex]m = y^{\prime}(3) = 3*3^2 - 3 = 27 - 3 = 24[/tex]

So the equation to the tangent line to the curve a the point is:

[tex]y - 20 = 24(x - 3)[/tex]

HELP PLEASE ILL GIVE 10 POINTS

Answers

Answer:

The answer would be 150 degrees.

Step-by-step explanation:

When looking at the problem you can see that you have two parallel lines and a transversal. Since the two lines are parallel, this allows alternate interior angles to form, i.e. <A and <B.

Since angle A and B are alternate interior angles, you can now set the two equal to each other.

So, in order to find out what x equals, you have to set the two equations equal to each other.

8x-10=3x+90

Next, solve the new equation.

8x-10=3x+90

Add 10 to both sides.

8x=3x+100

Subtract 3x from both sides.

5x=100

Divide both sides by 5 and you'll get your answer.

x=20

Now that you know what x equals, you can substitute it into the equation for B.

<B= 3(20)+90

60+90= 150

<B=150 degrees

That gives you your answer of <B = 150 degrees.

To check your work you can also substitute x into the equation for <A.

<A= 8(20)-10

160-10= 150

<A=150 degrees.

Therefore, you have just proved that the answer is 150 degrees.

In the figure below, lines A and B are parallel. Find the m∠5 if m∠1 = 75° and m∠3 = 40°

Answers

Answer:

Angle 5 is 75 degrees

Step-by-step explanation:

angle 1 is congruent to angle 5

so angle 5 is also 75 degrees.

The measure of angle 2 and 5 are 65° and 85° respectively.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

Given that, lines A and B are parallel.

Here, m∠1 = 75° and m∠3 = 40°

Now, x+m∠2+m∠3=180°

x=m∠1 (Vertically opposite angles)

x=75°

75°+m∠2+40°=180°

m∠2+115°=180°

m∠2=65°

m∠2=m∠4=65° (Interior alternate angles are equal)

Now, m∠4+m∠3+m∠5=180°

65°+40°+m∠5=180°

m∠5=85°

Therefore, the measure of angle 2 and 5 are 65° and 85° respectively.
